EVP_PKEY_CTX_get0_pkey() is used to access the EVP_PKEY associated with the given EVP_PKEY_CTXctx.  The
       EVP_PKEY obtained is the one used for creating the EVP_PKEY_CTX using either EVP_PKEY_CTX_new(3) or
       EVP_PKEY_CTX_new_from_pkey(3).

       EVP_PKEY_CTX_get0_peerkey() is used to access the peer EVP_PKEY associated with the given EVP_PKEY_CTXctx.  The peer EVP_PKEY obtained is the one set using either EVP_PKEY_derive_set_peer(3) or
       EVP_PKEY_derive_set_peer_ex(3).

       an EVP_PKEY_CTX

EVP_PKEY_CTX_get0_pkey() returns the EVP_PKEY associated with the EVP_PKEY_CTX or NULL if it is not set.

       EVP_PKEY_CTX_get0_peerkey() returns the peer EVP_PKEY associated with the EVP_PKEY_CTX or NULL if it is
       not set.

       The returned EVP_PKEY objects are owned by the EVP_PKEY_CTX, and therefore should not explicitly be freed
       by the caller.

       These functions do not affect the EVP_PKEY reference count.  They merely act as getter functions, and
       should be treated as such.
